The steps to add an auto responder are:

1. If you have not created the email user that you would like to have the autoresponder on, add it. The help on adding an email user is at: http://www.precisionweb.net/SelfHelp.htm#email
2. Once you have added the user (or if you have an existing email user account that you would like to add an autoresponder to)  click on the envelope icon to the right or the user. From the email settings screen put a check mark next to "Vacation Message". Then in the text box to the right,  type in the message that you would like to be sent automatically. Then click the Save Changes button.

Once it is set up, and email sent to that address will get an automatic response emailed back. This can also be used with information request forms to automatically have the information mailed to the customer.
